ABSTRACT
Using the extended tight-binding model that allows bond lengths and angles to vary, the optical transition energies Eii in single-wall carbon nanotubes are calculated as a function of inverse tube diameter. After geometrical structure optimization, the 2n+m=constant family behavior observed in photoluminescence (PL) experiments is obtained, and detailed agreement between the calculations and PL experiments is achieved after including many-body corrections.

    We report on the ‘on-line’ photoluminescence (PL) detection of individual single-walled carbon nanotubes (SWNTs) in water-surfactant dispersions. This was achieved by using a near-infrared confocal laser luminescence microscope specially optimized for the PL spectroscopy of SWNTs ....

    The authors report the effect of ultraviolet (UV) illumination on optical properties of single-wall carbon nanotubes (SWCNTs) isolated using various dispersants. It is demonstrated that even weak UV light (∼1 mW/cm2) can irreversibly alter the SWCNT structure, thus resulting in the...

    In this review, the organic cycloaddition and complexation of transition metal oxides with alkene, diamond (100), fullerene and carbon nanotube have been summarized. A clear scenario that analogous chemistry reaction is able to occur in materials featuring an analogous bonding motif has been...

    Abstract. Y-branching was observed by scanning tunnelling microscopy (STM) in single wall carbon nanotubes grown by thermal decomposition of C[sub 60] fullerene in the presence of transition metals. These novel carbon nanostructures may play an important role in carbon-based nanoelectronics.

    Label and label-free methods to image carbon-based nanomaterials exist. However, label-based approaches are limited by the risk of tag detachment over time, and label-free spectroscopic methods have slow imaging speeds, weak photoluminescence signals and strong backgrounds.

    We report interesting observation of strong enhancement of ultraviolet luminescence from hybrid structures of single-walled carbon nanotubes (SWNTs)/ZnO. SWNTs of 3–120 nm thickness (t) were deposited on top of 100 nm ZnO films/n-type Si (100) wafer by spin coating and vacuum filtration...
